CROSSING-SIGNAL FOR RAILWAYS.

Specification of etters Patent.

Patented March 26, 1907.

Application filed August 6, 1906. Serial Nm 329,332.

To LZ/f whom it may concern:

Be it known that 1, JAMES CRUMLEY, a citizen of the United States,residing at Grand Rapids, in the county of Kent and State of Michigan,have invented certain new and useful Improvements in Crossing-Signalsfor Railways, and l do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to improvements in crossing-signals for railways,and more particularly to such devices as are shown in my Patent No.750,264, of January 26, 1904; and its object is to provide improvedmeans for transmitting motion from the lever engaged by the whee s ofthe railway-train to the bell when the same is located at a considerabledistance from the lever and to provide the same with various new anduseful features hereinafter more fully described, and par? ticularlypointed out in the claims.

My device consists, essentially, of the combination and arran ement of alever depressed by the whee s of a passing train, a bell located at adistance from the lever, and a series of separate wires connecting thelever and bell, and pendulum-hangers supported at intervals between thelever and bell, the points of connection of the respective ends of thewires extending from one hanger to the next, being arranged at differentdistances from the pivot of the hangers, whereby these hangers operateas levers to increase the longitudinal movement of the wires, the lastwire in the series being connected to a tension-spring and to the bell,whereby a slight movement of the lever will operate the bellsuccessfully at a long distance from the same, as will more fully appearby reference to the accompanying drawings, in which- Figure 1. is a sideelevation of a device embodying my invention, with parts broken away gFig. 2, a plan view of the same; Fig. 3, a detail of one of thependulum-hangers and the sup orting-post; Fig. 4, the same of the bellandp support for the bell, and Fig. 5 an enlarged detail of theoperating-lever and` stop-shoulders for the same.

Like numbers refer to like parts in all of 1 he figures.

1 represents any convenient bell for sounding an alarm to indicate anapproaching train.

2 is a flexible arm on which the bell is suppolrlted, the vibration ofwhich arm rings the be 3, 4, and 5 represent a series of supportingpostsfor the bell and the various pendulumhangers, which posts are spacedapart at convenient distances along the railway to locate the bell at aconsiderable distance from the operating mechanism, whereby theapproaching train will give warning of its approach a sufficientdistance in advance by the ringing of the bell.

The mechanism for ringing the bell consists of a bed-plate 6, attachedto the outer end of a tie adjacent to one of the rails and provided'withjournal-bearings 7, in which is a rock-shaft S, on one end of whichshaft, adjacent to the rail and projecting slightly above the plane ofthe same, is a lever 9 to operate the rock-shaft. This lever is providedwith a shoulder 9a, which engages a projection 7a on the adjacentbearing 7 to limit the upward movement of the lever and stop the sameslightly above the plane of the rail. The opposite end of the rock-shaft8 is provided with a crank-arm 10, to which arm is attached a wire orcord 11, which is the irst of a series, indefinite in number, (two ofwhich are shown at 12 and 13,) of separate wires or cords suilicient toextend to a contractile spring attached to the bell-supporting post,which spring maintains tension on the series of connecting-wires andyieldingly holds the lever 9 in elevated position. To transmit motionfor a considerable distance through this series of wires and to increasethe amplitude of this movement, I provide supporting pendulum-hangers17, pivoted at their upper ends, as at 19, to the various posts andprovided with two or more openings 18 near their lower ends, in whichare inserted the adjacent ends of the wires 11 12, and 13, the end ofeach wire in the direction of the lever 9 being attached at a greaterdistance from the pivot than the end of the same in the direction of thebell. The hangers thus operate as levers to amplify the longitudinalmovement of the wires, and thus enable the device to operate the bellsuccessfully at a considerable distance from the lever mechanism. Tovibrate the bell, a branch wire or cord 15 extends from the last wire inthe series,from near where it attaches to the spring 14, to thebell-hangers 2, and thus imparts motion to the same from the IOO TIO

Wires 13 as the same is vibrated longitudinally by the engagement of theWheels of a passing train With'the lever 9. By this ampliiyingarrangement I am also able to operate the device with but very slightmovement of the lever 9, and thus the device will operate successfullywhen engaged by a rapidly-moving car-Wheel. It Will also be noted thatby the described device I am able to utilize the ordinarytelegraph-poles to support the hangers and bell, thus saving the expenseof separate poles or posts for the same.

What I claim is- 1. In a signal of the class described, the combinationof a bell, a lever engaged by the Wheels of a passing train, a series ofseparate Wires extending 'from the lever to the bella ndpendulum-hangers to which the respective ends of the Wires are attachedat different distances 'from the pivots of the hangers to amplify themovement of the Wires.

2. In a signal of the class described, the

combination of a pivoted lever adjacent to the track of a railway, abell located at a distance therefrom, a series of hangers between thebell and the lever, and a series of separate Wires connected to thelever and to the bell, said wires being connected to the respectivehangers, with their ends nearest the bell at a greater distance lfromthe pivots of the hangers and their ends nearest the lever at a lessdistance from said pivots, whereby the hangers operate as levers toamplify the longitudinal movements ol' the wires.

3. In a signal of the class described a rockshalit near the rail olt arailway, a lever ixed on the shalt, and ]')rojeeting above the plane Yof the said rail, stop-shoulders to limit the upward movement of' thelever, an arm on the rock-shalt, a bell located at a distance from therock-shaft, a series ol" segmrate Wires connecting the arm and bell, aseries ol' pivoted hangers to which the reswctive ends of the wires areattached at dilIerent distances from the pivots ol'A the hangers, atension-spring att-ached to the wires, and means for connecting` thebell with one elE the wires. In testimony whereof I ailix my signaturein presence of two witnesses,
